FLUSH-VALVE FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 485,155, dated October 25, 1892.

Application filed May 11, 18921 $erial No. 32,571. (No model.)

To aZZ whom it may concern:

Be it known that I, EDUARD HERDEGEN, a subj ect ofthe Emperorof Germany, residing in the city of New York, county and State of New York, have invented a new and useful Improvement in Flush-Valves for VVatenOlosets, of which the following is a specification.

The object of my invention is to provide an additional flush-valve for water-closets, where:

by when the ordinary flush-valve generally in use is closed a specified amount of water will at once continue to flow through the closet while being used.

The invention consists in the improved :5 flush-valve and the arrangement and combination of its various parts and its connection with the valve-operating mechanism, substantially as hereinafter described and claimed.

Referring to the drawings, in which like letters indicate similar parts, Figure 1 is a longitudinal vertical section of a water-tank on line 1 1, Fig. 2, a portion of the water-pipes and flush-valves being also shown in section; and Fig. 2 is a partial top view of the tank.

In the drawings, A represents a water-tank divided by a vertical partition 13 into two chambers O D, the partition B extending nearly to the top of the tank, so as to leave an overflow-opening E from the receivingchamber D.

Upon a bar F, extending across the top of the tank or other support, is secured in any desired manner an upright G, on which is fulcrumed a lever H, pivoted at one end with an adjustable Weight I, the other end being adapted to be connected with a rod or chain J, the lower end of this rod or chain being preferably connected to the seat of the watercloset. "Water enters the receiving-chamber D through a pipe K, and the height of water in this chamber is regulated by an ordinary ball-valve in the pipe K or by analogous means, but not shown in the drawings.

To the arm H of the lever H is connected a rod or chain L, to the lower end of which is secured a valve M, adapted to open and close the valve-seat in the bottom of the chamber O, which valve-seat is at the top of the main flushing-pipe U.

Extending from the chamber 0 into the lower part of the chamberD through the partition B is a small chamber P. In the plate forming the top of the chamber P 1s an aperture leading into the chamber D, which 1s opened and closed by means of a valve (n02 shown) connected by rod R with the arm H of lever H. This valve and connecting-rod are inclosed in a pipe S, rigidly secured over the aperture in the top plate of the chamber P. The main pipe Uis connected bya coupling T with a pipe 0, extending to the chamber D and opening into a vertical pipe a within the chamber D. The upper end of pipe at is or may be threaded to receive a threaded valve-seat 0, having cross-bar d with central opening to guide a valve-stem e; but the valve-seat c and bar cl may be directly on pipe a.

f is a disk-valve adapted to rest upon the cross-bar d when the valve is closed, as shown in Fig. 1. A short distance above the disk f is a larger disk g, adapted to rest upon the top edge of the valve-seat c and forming between the disks f and 9 an annular channel, 1n whlch 7 5 is or may be placed a water-tight packmg h. The disk 9 is secured to the lower end of an upright tube or rod j, which is contained within a vertical shell lo and adapted to sl de vertically therein. The upper part of this shell 7a is by preference closed by means of a cap m. The extent of movement of the shell k on the valve-holder 3', or vice versa, is controlled by a vertical slot at in the side of the tube j, which receives a screw or pin 0, secured in the shell in. The top of the cap m connects bya rod or chain 13 with the arm H of the lever 11.

In the position shown in Fig. 1 the water closet seat is unoccupied, the valve M being 0 opened and the valves in pipes S and a closed.

In this condition the water in the chambers C and P will pass through the pipe U 1nto the Water-closet basin, and meanwhile the chamber D will be filled to its predetermined height through the pipe K. hen the rod or chain J is drawn down by pressure on the water-closet seat or by any other means, the arm H of the lever will be moved downward, closing the valve M, while the arm I11 will be moved upward, opening the valve 1n pipe S and lifting the shell is and valve-holder 7. In

I finally rests on the seat 0.

this position, therefore, the valve M will be closed and the valves in the pipes S and a w1ll be opened. Water will then flow through chamber P into chamber 0. The valve g on the pipe (1 being also open, water will also flow through the opening formed between the disk 9' and valve-seat 0 into pipe at and thence through pipes O and U to the water-closet basin. moved, the lever H will at once resume the posltion shown in Fig. 1. The shell 7c will also be lowered and the valve-holder j within it Will gradually slide down until its valve 9 The valve M being opened at the same time, the water in the chamber 0 will pass through pipe U to the water-closet basin.

By my improved flush-valve I am enabled to flush the closet-basin while the closet is in use and the seat is pressed down instead of the flushing being confined to the time when the pressure on the seat is removed-that is to say, as soon as the seat is occupied water will flow through the pipes a O U into the basin. At the same time by opening the valve in S the chamber 0 will be filled, and when afterward the seat is released the water will be gradually shut off by closing the valve g, while the full flushing process is secured by the opening of the valve M. This feat-ure'of allowing the valve g to be gradually closed is a valuable part of my invention and is ac complished by the water rushing through or between the valve-seat c and the verticallyinovable valve g, thereby partially support- VVhen the pressure on the seat is reing it and allowing it to only slowly regain its seat, which is not accomplished until some time after the shell is, together with the leverarm H attached thereto, have attained their normal position, whereby it will be seen that for some time after the seat or arm H is released the water will continue to flow from the chamber D, or even after the entire contents of the chamber 0 has been drawn ofii.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The combination of tank A, having partition B and chambers C, P, and D, with the water-discharge pipe U, valve M thereon, branch pipe 0, carrying upwardly-extending pipe a, shell 70, valve 9, loosely carried therein, whereby said valve 9 will not be seated until after the shell is and lever-arm attached thereto have regained their normal position, and valvechamber S, having a valve mounted therein, substantially as herein shown and described.

2. The combination of the pipe at with the valve 9, adapted to close its upper end, shell is, valve-stein 3', adapted to slide therein, and lever H, attached thereto, all arranged so that the valve g will be nnseated after the shell It has regained its normal position, substantially as herein shown and described.
